reservation of momentum
momentum before = after

0 = momentum of piece to the right + 2nd one

0 = 2.5(120) + (4-2.5)v

v is negative so it moves to the left

In a parallel circuit, what’s happens to the current through each resistor when the voltage is doubled?
34kurt

Answer:

A

Explanation:

Voltage, V = Current, I x Resistance, R  (V is directly proportional to I where R is constant of proportionality)

This means that when Voltage is increased, Current increases and when voltage is decreased, current decreases (and the inverse is true). Through all this though, resistance remains constant regardless.

What happens to the boiling point of water as you climb higher up a mountain?
Maksim231197 [3]
The higher the pressure, the higher boiling point of water. At lower the pressure, the boiling point of water comes down. So, the lower pressure inreases the boiling resulting more evaporation. As we go higher in altitude, the atmospheric pressure decreases. This results in decreasing the boiling point at higher altitude and increase in boiling of water. In fact, at the sea level ,the the sea water boils at 100 degree C where atmospheric pressre is normal. However , the boiling takes place at a lower temperature at the top of a mountain due to low pressure. In other words the boling is faster at the top of a mountain than that at its foot.

Pani-rosa [81]

Women have lower centers of gravity, and lower centers of gravity provide more stability.

<h3>What is centre of gravity with example?</h3>

The location in a system or body where the weight is equally distributed and all sides are in balance is known as the center of gravity. The middle of a seesaw is an illustration of a center of gravity. the center of mass of an object in a gravitational field that is uniform.

<h3>How can you improve your center of gravity?</h3>

Training your legs and lower body is essential since they contain the biggest muscles in your body, as any competent bodybuilder or strength athlete will tell you. Exercises like squats, lunges, and calf raises should be a regular part of your workout routine if you want to reduce your center of gravity.
